Background
The burden of severe haemophilia A (HA) has been studied extensively owing to the higher bleeding frequency and associated treatment requirements, leaving a clear unmet need for research focused on the burden of mild and moderate HA.
Aims
This study sought to characterise the clinical and psychosocial burden of mild and moderate HA in the Italian cohort of the CHESS II study.
Methods
This was a retrospective analysis of clinical and psychosocial outcomes in a cohort of male adults (≥18 years old) with mild or moderate HA who participated in the cross-sectional CHESS II study (October 2019-November 2020). Treatment patterns, acute and chronic clinical outcomes and mental health indicators were collected via physician-completed forms. Psychosocial outcomes related to impact of HA on social activities, exercise, opportunities, and lifestyle were collected via a participant self-complete questionnaire. All results were reported descriptively.
Results
A total of 113 people with haemophilia A (PwHA) were included, 79 (70%) with moderate HA and 34 (30%) with mild HA, with mean age of 41.4 and 36.6 years, respectively. No one in the sample was receiving a prophylaxis at the time of data capture, with factor VIII use in the 12 months prior reported in 30% and 29% of moderate and mild PwHA, respectively. Ninety-one PwHA (81%) experienced ≥1 bleeding event in the preceding 12 months. People with moderate HA had higher mean annual bleed rate (2.9 vs. 1.1, respectively) and higher prevalence of chronic pain (74% vs. 35%), anxiety (20% vs. 12%), and/or depression (15% vs. 3%). Target joints were reported in 22% and 12% of moderate and mild PwHA, and problem joints in 51% and 12%, respectively. Of 113 participants, 44 (39%) completed the self-complete form (moderate HA, 57%; mild HA, 43%). Overall, 40% vs. 10% of those with moderate vs mild HA reported reducing or giving up social activities, 44% vs. 21% reducing or giving up exercise, 36% vs. 26% missing out on opportunities, and 48% vs. 26% reported HA impacted their lifestyle.
Conclusion
Moderate PwHA from the Italian CHESS II cohort appeared to have greater clinical morbidity and lifestyle impact than mild PwHA. Psychosocial outcomes were also worse among moderate PwHA, but significant burden was also observed among mild PwHA. These findings, and the absence of prophylactic treatment in the sample examined, highlight that improving management for potentially undertreated mild/moderate PwHA may aid the avoidance long-term clinical morbidity and negative psychosocial impact.
